The neural cell adhesion molecule 1 (NCAM1) is a fundamental protein in cell-cell interaction and in cellular developmental processes, and its dysregulation is involved in a number of diseases . Title: Neural cell adhesion molecule 2 as a target molecule for prostate and breast cancer gene therapy. In this study, we used an adult zebrafish spinal cord transection model to test the functions of contactin-2 in spinal cord regeneration. Francis GS. Crossref Medline Google Scholar; 16. The neural cell adhesion molecule (NCAM) is involved in development of the nervous system, in brain plasticity associated with learning and memory, and in neuronal regeneration. NCAM regulates these processes by influencing cell adhesion, cell migration, and neurite outgrowth. The carbohydrate variations reflect a high and low content of polysialic acid, and for the two vertebrates examined the expression of these forms is similar. We conclude that identification of NCAM mimetics opens up novel prospects for elucidation of the role of NCAM in neural differentiation and plasticity and, therefore, for practical development of new tools useful for the treatment of . 1982 Feb 25; 295 (5851):693-695.
